White Goop In Oil Filler Neck *pics*
This has happened before. There is a slimy white goop in the oil filler neck. What is this? What causes this? Should I be worried about a blown engine?

just new to this forum and the rx7
but anything that looks like mayonaise in the oil is usually a mix of oil and water
the question is where is the water coming from?
if you are only driving short distances during winter then the moisture in the air drawn into the engine can be enough to cause minor amounts of white goo
and is why when for a few minutes after a car is started it will be blowing white steam and drops of water out the exhaust
however once the engine is up to temperatures above boiling point the moisture in the air will be boiled out and the oil should look clean, exhaust will also stop blowing steam as super heated water vapour can't be seen
SO, if you have a little mayo after a few weeks of short runs near freezing don't be worried
BUT, if you have lots of mayo there all the time, even after several drives of over half an hour, then you may have blown an O-ring

keep an eye on your coolant levels and the see if there is an oily film in your radiator water
